1/y=-9/px+1/p
reciprocate--> y=-px/9+p
write as single fraction--> y=(-px+9p)/9
cross multiply--> 9y=9p-px
rearrange--> 9y+px=9p

now the first one in the table-->
y=qy/x+p
now just multiply evrything by x ull get it

now the 2nd one-->
y/x=y/q-(p/q)
multiply evrything by q--> qy/x=y-p
cross multiply--> qy=xy-px
rearrange ull get it
 
and blah blah blah
